Kentucky
Geode Field Trip
[Click

We
left Broken Arrow, OK bright and early the morning of August 29th (4:00 am) and
headed for Kentucky to join members of the Catawba Valley club for a weekend of
geode and fossil collecting near Danville, KY. we drove the 860+ miles to my
sister's place in Ezel, KY, about 100 miles east of Danville, in around sixteen
hours, most of that in heavy rains and thunderstorms.
We spent the night at Ezel, and the following morning, Brandon and I headed for
Danville and the proposed meeting spot at around 6:00 am, arriving in Danville
at around 8:00 am. The rain had set in again, and kept up for some time that
morning as we met with the others at the Holiday Inn Express. I recognized Mike
right away from the picture on his book cover, and we met Chris, Opal, Harry,
Ernie, and several other members of the Catawba Valley club.
After a short pow-wow to decide which site to collect at first, we hit the road
headed south to the property of Mr. Phillips and the creek behind his house. The
rain let up by the time we arrived, and although the creek was running pretty
good, there was no shortage of geodes to be had, they were everywhere, ranging
from the size of a golf ball to larger than a basketball. In the following
picture you can see a large one sitting on the back of the truck.
Harry explained the general geologic features of the geode bearing layer above
the ancient sea bed which is now a gray shale layer overlain by sediments, where
the geodes formed either from pockets created by the escaping gasses from the
decaying sea bed, or by the slow dissolution of iron concretions that were
replaced by silica from the ground water. There are several theories as to how
the geodes form, all seem to have merit. After a several hours of wading the
creek, cracking geodes, shaking likely prospects to see if there were loose
crystals inside, and marveling at the sheer abundance of them, everyone was
pretty much ready to head back to town, dry off and get lunch. Brandon and I
loaded up a couple of hundred pounds of geodes, most unbroken, to take home and
cut. Many interesting formations were found inside the geodes, from clear quartz
crystals to pseudomorphs (quartz after calcite).
Quartz Geode and Pseudomorph.
After
lunch, we all met back at the Holiday Inn around 2:00 pm, and it was decided to
go look for fossils at an Ordovician outcrop about three miles south of
Danville. There wasn't much parking space available so Mike and I parked west of
the bridge below the road cut, while others parked alongside the cut in the
narrow space there. As you can see from these pictures, this is a large cut, and
there are several fossil bearing layers exposed in the hard shale. Some
specimens were found weathered out, while others had to be extracted. That's
Mike, Chris, and Opal in the third picture.

After
about an hour, the rain caught up with us again, and while everybody else headed
for dry quarters, Mike, Chris, and myself and Brandon stuck it out for a while.
Brandon and I watched Mike make rubble out of a rock shelf that had collapsed, a
rather large piece of limestone cap rock that had fallen from the upper layers
of the cut, looking for calcite vugs containing dogtooth calcite. We checked out
the rubble across the road and found Chris a nice slab of fossiliferous
limestone full of nice brachiopods to take home, a nice display specimen.
Eventually, the rain got the better of us, and Brandon and I finally decided to
head back to Ezel for the night. Mike and Chris were still poking around the
outcrop when we left.
The
following morning we got up bright and early, and loaded up in the Suburban,
myself, Brandon, Travis, (my 16 yr old, six-foot-seven offspring), my wife
Regina, and Butterbean (the six-week old holy terror of a kitten). We met back
in Danville at 8:00 am with the group and headed for the McClure farm at Crab
Orchard, KY. The weather held out for us most of the morning while we collected
more geodes, many similar to the ones from the previous day with a few
interesting exceptions, Some of these had boytroidal chalcedony in them.
Now don't let Mike fool you, he says I tell tall tales about him and his
escapades in the field, but he really does go after the biggest rocks with a
hearty vigor as the following pictures will attest. Look for the biggest rock in
the creek, that's the one Mike is wailing on with an eight pound sledgehammer
and two-foot chisel...

If I
didn't know better, I'd say I was getting a dirty look in that last one...
Harry and
Ernie got busy after a while and decided to get out the pipe cutter and crack a
few geodes. This gained some attention as everyone was getting tired of trying
to crack them with hammers, and this seemed to do a rather nice job of splitting
them open without doing a lot of damage.
The following picture #1 is Regina, Brandon, Harry's wife (Harry, correct me if
I'm wrong here!), Harry's father-in-law (87 years young!), Opal, and Butterbean.
Picture #2 includes Mike, and Travis (petting Opal).
Pictures #3 and #4 same folks.
Picture #5 is the group watching Harry and Ernie cracking geodes.
Picture #6 are some Catawba Valley club members.
Eventually, we had to vacate in a hurry, as there was a large severe
thunderstorm rolling in on us. We could hear the thunder and see lightening
strikes not too distant. Everybody loaded up pretty quick. and headed up out of
the creek bottom to beat the rain in from the field. Most of us made it back to
the road before the serious rain hit, Travis stayed down at the second gate to
close it for stragglers (no names here!) We made plans to meet at the Wal-Mart
in Stanton at 2:00 and head for our final stop of the day at Halls Gap, KY, for
geodes, hopefully with Millerite inclusions.
Again,
this is a rather large road cut at the top of a long grade.
The site was closed for a time due to dangerous overhangs and undercutting. The
state highway dept. finally came in and collapsed the cut for safety reasons,
mainly to ward off a rock slide which could endanger motorists. After this the
site was re-opened to collecting. Now, As I said before, Mike claims I tell tall
tales, especially about him. So rather than elaborate here, I'll just include a
few more pictures. Note that all of the dirt Mike is standing on in this next
picture was part of the vertical cut bank when we got there..
Now doesn't he look happy in
this picture? 
Below are
some more pictures of the time spent with great bunch of rock-hounds one
weekend in Kentucky. I can't think of a better way to spend a weekend than with
friends.

The
following picture is a bucket of geodes from the upper reaches of the cut
similar to the fluorescent one Mike posted, with luck there will be some of the
same in this batch. 
The
following is one of the geodes from the shale that was found at the bottom of
the cut, this one has quartz, boytroidal quartz, pyrite crystals, and under
close inspection, a couple of needles of Millerite. 
All in
all, everyone had a great time, and I am personally looking forward to the
opportunity to join the group next year for another geode splittin' good time in
Kentucky. Ya'll come back now, ya'hear?
